To aZZcohom it may concern:

q Be it known that l, THOMAS S. VInRow, a citizen of the United States, and-resident of Jersey City, in the county of Hudson and 6 State of New Jersey, have'invented certain new" and useful Improvements in Depositing Machines, of which the following is a specification.

My invention has reference to machines for bakery and confectionery purposes, such as for depositing batter or soft-dough for cakes and analogous articles.

The object of my invention is to provide simple and effective means for scaling and depositing the material in successive batches, whereby to enable the regulation in a simple manner of the volume of the deposits according to the size of the cakes or the like to be'produced.

My invention comprises novel details of 'improvementthatwill be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had in the accompanying drawings, forming a part hereof, *wherein 1F ig. 1 is a side elevation of a depositing machine-embodying my invention;

Fig. 2 is a detail of cut ed devices for the Fig 3 is a vertical of the machine;

Fig. 4 is a cross section on line it, 4 in Fig. 3; and p Fig. 5 is an end view looking from the right hand side of -Fig. 1, parts being omitted.

Similar numerals of reference indicate corresponding parts in several views.

e numeral 1 indicates the main frame of the machine which may be of any suitable construction. At "2.is indicated a hopper, suitably supported by frame 1, adapted to contain the material to be deposited, such as batter, soft dough, or the like. of the material thrdugh outlet 2 sectional detail of partof hopper 2 is controlled by valve member 3, shown in the form of a round bar having a recem 3* extending along one side. Valve member 3 is shown journalled in bearings beneath the hopper and said valve opposes a cyl nder 4 supported up themain frame. Cylinder a is shown provided between members 5 and J 6 which oppose and provide bearings for member 6 being shown provided with outlet 7 for the material to be deposited. Valve 3 is to be-rocked to present its recess 3 alternately in register with hopper 2 and cylinder 4 and with the cylinder and outlet 7. Said valve is shown provided with a crank-arm 8 pivotally connected with a lever 9 that is pivoted upon the main frame at 10 and provided with a projection or roller 11 co-operative with a cam groove 12 in cam member 12 that is secured upon shaft 13 suitably journalled upon frame 1. During each rotation of cam 12 the valve 3 will be rocked back and forth to receive material from hopper 2 and cut old material therefrom. A plunger or piston 114i is slidable in cylinder d. Plungerld is to be reciprocated with relation to the rec of valve 3. Thelength of the stroke of the plunger is to be regulated accor g to the dimensions of the deposits of material to be made. it have shown piston 14L pivotally connected at its sides near the outer end with spaced arms 15, as by means of pivots 16 connecting said piston with said arms, which arms have adjustable fulcrum points to vary the length of stroke of plunger 14 as desired.

The arms are shown provided in their outer surfaces with longitudinally disposed grooves or guideways 17 in which are located pins 18 shown within blocks 19 slidable in the corresponding grooves 17, which pins are connected with nuts or threaded blocks 20 (Fig. 4). Screws 21 are journalled at opposite ends in bear; in brackets or the like 22, 23, secured, as by screws, to opposite sides of frame 1, which screws operate in the threads of nuts or blocks 20. I provide means to rotate the screws 21 similarly and in unison to correspondingly simultaneously move the nuts 20 with their pins 18 alon the arms 15. F or such purposes I have own gears 24: secured on thescrews 21 and in mesh gears 25 secured on transverse shaft 26 journalled in bearings at27 on e 1, which shaft is provided with a handwheel or crank 28 for rotating it.

The lower ends of arms 15 are shown connected by a tie-rod 29 that is pivotally connected with .a link 30 that ispivotally connected with a crank 31 on shaft 13 to rock the arms 15 (Fig. 3). The nuts 20 will be adjusted along arms 15 by the rotation of screws 21 to determine the positions of the [LCD lit

fulcrum points of arms 15, at the pins 18, whereby the length of stroke of plunger 14 Will be regulate To provide packing atthe operating end of plunger 14, I insert a suitable packin strip 14 between the end of the plunger an a bar 14*, which bar is connected with a screw 14, which passes through a hole in the plunger and extends beyond its outer end, a locking nut 14 securing the screw in set position. By operating the screw 14 the bar 14? may be forced more or. less againstlpacking 14- to cause the latter to snugly fit in cylinder '4 to provide for proper suction with respect to material in the cylinder.

Valve 3 and plunger 14 are shown in the material discharging or depositing positions in Fig. 3. lVhen valve 3 is rocked in the direction of the arrow in Fig. 3, the groove or recess 3 of said valve will be presented in register with the hopper outlet 2 and plunger 14 will move outwardly, whereby material from the hopper will be drawn into cylinder 4. Valve 3 will next return to cut 'oli the outlet 2 andcause recess 3 to register with outlet 7, and plunger 14 will advance toward valve 3 to force material from,

' the cylinder through outlet 7 to be deposited,

and so on for each operation of valve 3 and plunger 14. i

When nuts 20 are in their lowest position,

shown in Figs. 1 and 3, plunger 14 will have its greatest stroke to depositex the largest amount of material, and in accordance with the position of nuts 20 above from said lowest position, the extent of rocking of the upper ends of arms 15 by means of crank 31 willbe determined for regulating the strokes of plunger 14 in accordance with the quantity of material to be deposited by the plunger. By the means described, I am enabled by the simple operation of 'rotatin the screws 21 to regulate the size of the eposits desired for each operation of the plunger. By means .of a pointer 32 on a nut 20 and a corresponding graduated scale 33 on frame 1 (Fig 1),

the position of nuts 20 along arms 15 may be determined with respect to various sized deposits to be made.

Any desired nozzle or nozzles 34 may be secured adjacent to outlet 7 to guide the material to pans or other receptacles 35, which nozzles may be replaced, as required; according to the sizes of the desired deposits. The nozzle 34 may be one continuous nozzle for a deposit, or may comprise spaced outlets of desired dimensions for simultaneously depositing several ortions of the material or batter, as well own in'the art. The nozzle 34 may be retained in place by the stop 35 and screws 36 (Fig. 3).

A cut-0d 37 is shown operative below noz zle 34, to oppose and open the outlet of the. nozzle. The cutofi 37 is pivotally supported \I names? at 38 to rock respecting the nozzle, which cut-off is shown provided with a crank. arm

39 connected by a' link 40 with a crank pin 41 connected to the valve 3. The relation oi the parts is such that when valve 3 is in the.

position shown in Fig. 3, the cutoli' 37 will,

beat one side of nozzle 34, and when valve 3' is rocked to register its groove or reee 3 with hopper outlet 2 the cut-ofl 37 1 be moved to close the outlet of nozzle 34.

- verse bars or slats 44 to support the pans.

The conveyor is shown mounted upon sprocket wheels 45, 46, carried by shafts 47, 48, supported upon a frame 49 that is journalled at one e (1 upon shaft 47, said shaft being journa led near its ends on frame 1. Frame 49 carries idle wheels 50, 51 bearing against the lower run of the conveyor. Shaft 48 is journalled near its ends in bearing boxes 52 guided in ways 53 on opposite sides ot' frame 49, which boxes connect .withscnews 54 journalled at their outer ends on frame 49., whereby. said bearing boxes may be adjusted in the ways 53 to provide the desired tension of the conveyor. A pinion 55 is secured on shaft 47 and is in mesh with a gear 56 so i connected to a ratchet 57 journalled on pinv or shaft 58on frame 1, a lever 59 rockable on pin or shaft 58 being provided with a dog 60 co-operative with ratchet 57. The lever 59 is pivotally connected by a link 60 with a crank pin 61 shown carriedby a nut or threaded block 62 supported upon a screw 63 that is journalled in bearings 64, 65, se-

rec

cured upon cam \member 12. Assaid cam member is rotated the pin-61 will cause lever 59 to rock, whereby the conveyor will be operated step by step toward the right in Fig. 1, the pans 35 being successively sto ped beneath nozzle 34 for each de osit or fischarge from said nozzle to be me e. The extent or travel of the conveyor .for each step thereof is in accordance with the dimensions of the uate slots 67 in ratchet57, whereby the po sition of stopping the conveyor respecting nozzle 34 may be regulated tolikewise stop the pans in desired position beneath the nozzle.

Means are providedto successively raise and lower conve or 43 and'trame 49 with respect to nozzle 4, such as by roch said v conveyor upon shaft 47 as an axis. For

rte

rat/rear such purpose I have shown a screw 68 pivotally connected to the conveyor frame 49 by pivot 68, which screw operates through a block 69 having projections 70 situated in recesses 71 in a lever 72 pivotally supported upon frame 1 at 73, the opposite end of said lever being shown provided with a projection or roller 74 to cooperate with a cam 75 secured on shaft 13 (Fig. 1). A nut 76 on screw 67 is adapted to bear against block 69. By rotating said nut upon screw 67 the position of conveyor 43, with respect to nozzle 3a, may be regulated, since the position of lever 72 with respect to said nozzle is predetermined. The relation of the parts is such that when a deposit is made in a pan, the lever 72 will raise the conveyor with the pan toward nozzle 34, and when plunger 14: has discharged the material from the nozzle the lever 72 will rock to depress the conveyor and thereby cause the material that may project from the nozzle to be broken away from the nozzle.

It will be noted that the cylinder 4 and plunger 14 are horizontally disposed with respect to the hopper, which has the advantage of not requiring the material from a hopper to be elevated by the plunger on its outward stroke, hence such material is not resisted by gravity, and the quantity of material drawn at each outward stroke of the plunger is accurate, so that dependence may be had that the deposits will be uniform to Within sufhciently accurate requirements.

lVhile I have shown two arms 15 with corresponding pins 18, nuts 20 and screws 21, it will be understood that I may provide a single arm 15 with its corresponding pin, nut and screw preferably located centrally with respect to plunger 14.
